Title: Laser piercing processing device for printed wire plate board
Inventor: TANI MAKOTO
IPC: B23K26/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a piercing processing without causing a thermal damage to a conductor layer when it is conducted with a TEA-CO2 gas laser oscillator to a printed plate board, by specifying the pulse width of a pulse form laser at a given range. SOLUTION: The pulse width is defined as a time during which an integrated energy value reaches 90% from 10% since the low energy parts, such as the one immediately after the oscillation is started, and at its tail end, do not contribute to the processing at the actual piercing processing. Based on the definition, the pulse width is set substantially at 3-4 μsec. When the piercing processing is conducted to a printed wire plate board by a laser with the pulse width of this kind, a resin layer of the printed wire plate board is removed by the laser at its peak output height, and a thermal damage to a copper hoil is prevented by changing it to a short pulse. Furthermore, in the laser chamber of the TEA-CO2 gas laser oscillator, a mixed gas of CO: 4%, CO2 : 8%, N2 : 16% and He: 72% is used as a gas component.

Title: Robot controller
Inventor: NUMAOKA CHISATO
IPC: G05D1/02
Filed: 1992-05-27
Abstract: PURPOSE:To control an autonomous robot so as to be gradually converged at real time in a suitable ratio to the target of a specified type while distinguishing the type of the target. CONSTITUTION:An autonomous robot 1 receives data sent from the respective targets with a communication equipment 2, and a vector 4 is constituted to show the number of autonomous robots selecting the respective targets before fixed time. A target selector 5 calculates a gain to each target with a gain function based on the vector 4, selects the target and sets the position coordinate of that target to a target position coordinate register 7. A track corrector 10 performs track correction by deciding a rotating angle corresponding to the target direction of the robot from the value of the target position coordinate register 7 and the value of a current position coordinate register 8. The forward movement of the robot is instructed by sending signals from the track corrector 10 to a driving device 11. Further, the value of the current position coordinate register 8 is updated by the forward movement.

Filed: 1981-08-28
Abstract: PURPOSE:To stabilize the rotation of a Hall element motor by disposing the Hall element to have an electric angle of 1/2 of that of a drive coil with respect to the dirve coil and pulsating the AC output of the Hall element, thereby digitizing the energizing control. CONSTITUTION:In a 4-pole stator motor, a sensor (Hall element) 40 is disposed so as to become 45 deg. of an electric angle with respect to the pole positions of drive coils L1-L4.

IPC: B29K23/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a crosslinked polyolefin tube having excellent pressure resistant creep strength by controlling a molecular structure in a molding by a simpler method than a prior art. SOLUTION: In the case of water crosslinking a polyolefin tube extrusion molded by melt kneading a mixture made of polyolefin resin, silane compound and radical generating agent, a pressure difference is applied between an inner surface and an outer surface of the tube to advance water crosslinking while applying a circumferential force of 0.5 to 8 MPa to the tube. As the polyolefin resin, single polymer of ethylene, ethylene and -olefin copolymer, single polymer of propylene or ethylene and propylene copolymer is used. The used silane compound is silane compound having an olefin unsaturated bond and hydrolyzable organic group. A stress is generated in a circumferential direction of the tube by the pressure difference between the outer surface and inner surface of the tube. Orientation of the tube in the circumferential direction is generated by the pressure difference.  Orientation of graft molecule is induced by the stress. That is, crosslinking chain is oriented in a thickness direction of the tube, and water crosslinking is advanced in this state. Accordingly, the obtained crosslinked polyethylene tube is improved in the stress of its thickness direction.

Title: Air conditioner and assembling the same
Inventor: YOSHIDA YUJI
IPC: F25B1/00
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To make an additional charge of refrigerant accompanied by connection of a long pipe unnecessary by using a connecting member as well as a fixed throttled member when the piping connecting member for connecting liquid lines has a length not less than a specified length. SOLUTION: When a liquid side pipe line 12 for connecting a liquid line to a liquid line has a length not less than a specified length set in advance, the liquid lines are connected to each other by the liquid side pipe line 12 and a pipe line 15 having a capillary tube 14 as a fixed throttled member from an outdoor unit 6 side having an expansion valve 4. When the liquid side pipe line 12 for connecting the liquid pipe lines to each other has a length not more than the specified length set in advance, the pipe line 15 is not used and only the liquid side pipe line 12 is used. In this structure pressure of refrigerant which has been condensed and liquefied in an indoor heat exchanger of an indoor unit 7 is once reduced by the capillary tube 14 and further reduction of pressure is effected by the expansion valve 4.  Therefore, the liquid side pipe line 12 between the capillary tube 14 and the expansion valve 4 is filled with the refrigerant in two phase. Addition of the refrigerant becomes unnecessary.

Abstract: PURPOSE:To decrease the number of input terminals and to prevent noise production by using the dynamic scan system using a microcomputer when 2 series of operation inputs exist for the control of two mechanisms. CONSTITUTION:The level of an input terminal IN6 goes to an L level as soon as input terminals IN1-IN5 of an electronic circuit 1 such as a microcomputer or a gate array go to an L level, then it is discriminated that operation input switches 16-20 of the 2nd mechanism are closed to control the 2nd mechanism, and while the level of the input terminal IN6 remains H level, the 1st mechanism is controlled. When the PLAY (reproduction) switches 12, 17 of the 1st and 2nd mechanisms are depressed simultaneously, the 2nd mechanism is controlled, but in providing two mechanisms normally, either of them has priority usually and the 2nd mechanism has the priority in this case.

Filed: 1986-06-11
Abstract: PURPOSE:To eliminate the need for a cassette height restricting pin by using part of a casing of a switch for detecting a detected part as a support face of a loaded tape cassette. CONSTITUTION:The rear height restricting face 8 of the cassette is formed by making the upper face of the casing of a detection switch 4.
